Computers & Business Machines

Imagine the loss, 100 years from now, if museums hadn't begun preserving the artifacts of the computer age. The last few decades offer proof positive of why museums must collect continuously—to document technological and social transformations already underway.

The Museum's collections contain mainframes, minicomputers, microcomputers, and handheld devices. A Cray2 supercomputer is part of the collections, along with one of the towers of IBM's Deep Blue, the computer that defeated reigning champion Garry Kasparov in a chess match in 1997. Other artifacts range from personal computers to ENIAC, the Altair, and the Osborne 1. Computer components and peripherals, games, software, manuals, and other documents are part of the collections. Some of the instruments of business include adding machines, calculators, typewriters, dictating machines, fax machines, cash registers, and photocopiers

This Black Apple, model number A2S1048B, was a version of the Apple II Plus made by Apple Computer, Inc. and sold only to educational institutions by Bell & Howell, at that time a company specializing in audiovisual equipment. It earned the nicknames "Black Apple" and "Darth Vader" because its case was black instead of the usual beige color of the Apple II Plus. To make the computer more versatile, Bell & Howell added audio and video slots onto the Apple II Plus and also made it UL-compliant. By allowing Bell & Howell to sell their modified product, Apple was able to succeed in the educational market.

In 1977, Commodore introduced the PET (Personal Electronic Transactor) home/personal computer. Appearing before either the Apple II or the Radio Shack TRS80, it was among the first personal computers. The PET 2001, Commodore's first model, included 4 kilobytes of memory, cost $495, and was fully functional out the box. The computer sold well, but initially Commodore could produce only a meager 30 units a day.

The PET had a main board with a 1 MHz MOS 6502 processor and room for additional RAM. The machine included a built-in cassette on the front of the case for data storage. Users could write their own programs in BASIC, but many complained about the small keyboard, which made touch typing difficult. The screen of the PET computer was small (9"), and had a black or blue display. Users could design simple graphics, do animations, or work out math problems. A notable feature of the PET 2001 was that the top of the computer opened for maintenance--like the hood of a car.

PET 2001 was designed by computer pioneer Chuck Peddle. He came to Commodore during the company's acquisition of MOS Technology in 1976. AT MOS, he had designed the KIM (Keyboard Input Monitor) computer. At Commodore, he convinced managers that computers were "in" and won approval to design the PET. It paved the way for later Commodore machines, such as the Commodore-64.

This particular PET 2001 was donated by Louis Mittleman, who noted not only that the keyboard was a serious "drawback," but also that the manual did not have much information.

Not long after Intel introduced its 8080 chip, a small firm in Albuquerque, New Mexico, named MITS (Micro Instrumentation and Telemetry Systems) announced a computer kit called the Altair, which met the social as well as technical requirements for a small personal computer. MITS succeeded where other, more established firms had failed, and it was their machine that inaugurated the personal computer age. MITS got its start in computing in 1971, when it introduced an electronic calculator kit. Several thousand sold before 1974, when the sharp reduction in calculator prices drove the company out of that market.

H. Edward Roberts, the Florida-born former U.S. Air Force officer who headed MITS, decided to design a small, affordable computer around the Intel 8080. His daughter named the new machine after the star Altair. It was the first microcomputer to sell in large numbers. In January 1975, a photograph of the Altair appeared on the cover of the magazine Popular Electronics. The caption read "World's First Minicomptuer Kit to Rival Commercial Models." According to the magazine, the machine sold as a kit for $395, and assembled for $498. Roberts had hoped to break even by selling 200 Altairs. Within three months he had a backlog of 4,000 orders.

The kit offered by MITS represented the minimum configuration of circuits that one could legitimately call a computer. It had little internal and no external memory, no printer, and no keyboard or other input device. An Altair fitted out with those items might cost $4,000—the equivalent to the cheapest PDP-8 minicomputer, a reliable and established performer. Most purchasers found the kit was difficult to assemble, unless they had experience with digital electronics and a workbench fitted out with sophisticated test equipment. And even if one assembled the kit correctly it was sometimes difficult to get the Altair to operate reliably. Gift of Forrest M. Mims III

When the TI-99/4a was introduced in 1981, Texas Instruments claimed it was both "a major breakthrough in computer technology," and, probably more important, the "lowest priced, 16-bit computer available." It cost only $525. The TI 99/4a was a redesign of the TI-99/4 system, which had been a market failure and was discontinued. The new machine sold well, but by August 1982, TI was falling behind its competitors, especially Commodore. So it began offering a $100 rebate on the TI-99/4a. It quickly became the best-selling home computer in America, controlling, by the end of 1982, approximately 35% of the market--150,000 machines a month.

In February 1983, TI cut the price to $150, and then in June 1983, it offered a plastic version of the TI-99/4a for less than $100. But now it had gone too far. It was selling computers for less than cost, resulting in a second quarter loss of $100 million.

The TI-99/4a operated on a TI TMS99000 at 3 MHz and included 16 KB of RAM and 26 KB of ROM. The computer included a RS-232 interface card and a 32K memory expansion card as well as a Data Storage cassette. Texas Instruments controlled the development of software for the machine and offered only around 300 titles. These did not include many of the most popular programs of the time.

Initially, the only way to expand the machine was to use a port on the right side of the console. Peripherals could extend out several feet. To remedy the situation TI released a more convenient Peripheral Expansion Box (PEB) and, surprisingly, sold 250,000 units at $1,475.00 each--far more than the cost of the computer.

Eventually Texas Instruments sold over 2.5 million units of the TI-99/4A. However the company decided that computers were not a promising business and dropped out of the PC market in 1984.

The Altair 680 appeared about a year after Micro Instrumentation and Telemetry Systems (MITS) had introduced the Altair 8800, which many historians credit as the beginning of the home computer industry. In the Altair 680, MITS offered an update of the Altair 8800 that was based on the Motorola 6800 processor.

Like the Altair 8800, the Altair 680 was a kit. For $293, users received circuit boards, capacitors, resistors, transistors, diodes, a power supply, an instruction manual, and a case in which to assemble it. Also like the 8800, the 680 had switches on the front that could be used to enter computer instructions, bit by bit. If customers were willing to pay $420, they could buy the computer already assembled. Neither the kit nor the assembled computer came with display, keyboard, or external storage device.

The Motorola 6800 microprocessor ran at 500 KHZ, and the computer had a 1 KB of RAM and 1 KB of ROM, as well as support for a serial terminal and punch reader.

The Altair 680 did not meet with the success that the 8800 had. Most users were now interested in buying computers that came with displays and keyboards, and were willing to pay more for them. The Altair 680 kit in the Smithsonian was never assembled.

Data General was primarily a mini-computer company. But in 1984, it introduced the Data General-One (DG-1), a breakthrough personal computer laptop. The Data General One weighed nine pounds, ran MS-DOS, had dual 3 ½" diskettes, 79-key full stroke keyboard, 128 KB to 512 KB of RAM, and a monochrome LCD screen. It ran on a CMOS 80C88 processor. Unlike other "luggable" computers of the era, the DG-1 was light enough to carry on travel, but also powerful enough to emulate a desktop.

The DG-1 enjoyed only mediocre success. Its 3 ½" diskettes were slightly ahead of their time, and much popular software was not available in 3 ½" format. Adding to the problem, software copyright protection made copying into the 3 ½" format difficult. In addition, the DG-1 base price was relatively high at $2,895, and the real cost tended to be even higher, because users generally needed both more RAM and an external 5 ¼" drive to run disks from their desktop machines.

Introduced in 1983 at a cost of $199.95, the Timex-Sinclair 2068 (TS 2068) was the Timex Sinclair's fourth and last personal computer for the US market. It followed the ZX81, TS 1000, TS 1500, and the ZX Spectrum.

The TS 2068 used a Z80 processor that ran at 3.58 MHz. Its memory included 48 KB of RAM and 54 KB of ROM. A cassette recorder was used for external storage. Like the TS 1000, the 2068 included a BASIC interpreter to run programs. Additional functions had been added to handle more complex graphic and sound commands. The TS 2068 included a sound chip and speaker at the bottom of the computer and had a range of 10 octaves and 130 semitones directly programmable from BASIC. Users could buy a TS 2400 printer that was attached to an expansion port.

The TS 2068 was well equipped for playing games and was compatible with all software designed for the ZX Spectrum. The computer was generally used for entertainment, educational, and programming tutorials.

Commodore International announced the Commodore Plus/4 in January 1984 as the Commodore 264. It was a more powerful sequel to the highly successful Commodore 64. The original concept was to sell the 264 in one of several different configurations. The consumer would select the type of application software they wanted to build in their computer, and the dealer would install the appropriate ROM chip. By the summer of 1984 this concept was abandoned. The name was changed to Plus/4, the computer was sold at the cost of $299, and all applications were added at the factory.

The Plus/4 was billed as the: "productivity computer with software built in." The Plus/4 has a MOS processor which ran at 1.76 MHz. It contained 64 KB of RAM and 64 KB of ROM. The Plus/4 had a built in MOS Technology 6551 UART chip which allowed the Plus/4 to use high speed modems without additional software. The computer included Commodore BASIC 3.5 and such software applications as a word processor, spreadsheet, database, and graphing. Inclusion of these four applications led to the computer being called the "Plus/4."

The machine was discontinued in 1985 when it failed to achieve the company's sales goals.

In 1987, Commodore introduced the Amiga 500, also known as the A500, as an inexpensive version of a 16 bit multimedia home computer. The goal was to provide a machine that would compete successfully against other 16 bit machines, just as the Commodore 64 had outsold many competitive 8 bit computers. The A500 did sell well against the Atari 520ST and was the low end successor of the Amiga 1000.

The A500 used a Motorola 6800 microprocessor that ran at 714 MHz and had 256 KB of ROM and 512 KB of RAM, which was expandable to 9MB. The Amiga 500 used a special system for its RAM configuration. It had 512 KB of Chip RAM, which could be accessed by the sound and video custom chip, and FAST RAM, which could only be accessed only by the CPU.

The Amiga 500 was followed by the Amiga 500+. It doubled the amount of the A500s Chip RAM to 1 MB. Both versions could be connected to a TV set or to a video monitor. The A500 computers were the best selling in the Amiga series. Besides doing well in the United States, they also were popular in Europe. Many users favored the Amiga because, in addition to being inexpensive, it had excellent graphics and sound capability for a computer of its era.

Pronto Systems, Inc. introduced its Pronto Series 16 computer in 1983. It represented the high end of business computing of its era. The Pronto pioneered innovative design features, including a tilting and swiveling monitor, small foot print, a streamlined and adjustable keyboard, and an expandable cord that allowed the processor to be stored as much as six feet away from the monitor. These features won a 1983 design award from Industrial Design Magazine. The computer offered the first tower system—a design that later became common in the industry.

Inside, the Pronto 16 was a powerful machine designed for the full range of business applications. It had a 16-bit Intel 80186 microprocessor. It was shipped with MS-DOS 2.0. It had 128 KB of RAM, which could be expanded to 1 MB. The standard hard drive was 5.6 MB, and it was removable. The computer had dual 800 KB floppy drives (5 ¼"), dual serial ports, one parallel port, and a high-resolution monochrome monitor. Users could buy a color monitor as an option. Base price was $3,000.

Over 1,000 systems were sold from 1983 to 1987. The company had to file for bankruptcy when the stock market crashed while the company was in the process of going public through an Initial Public Offering.
